The term “vacation” generally refers to a woman’s menstrual period. If you have not had your period for more than a year, and then you have bleeding, this is abnormal vaginal bleeding, not normal menstruation, which may be caused by high estrogen levels or gynecological diseases. 1. High estrogen level: If you usually take drugs containing estrogen, it is easy to stimulate the estrogen level to rise, stimulate the endometrium to thicken, if the endometrium appears to fall off, it is easy to lead to abnormal vaginal bleeding. 2. Gynecological diseases: If bleeding occurs again after menopause, endometrial polyps, endometrial cancer, cervical lesions and other factors should be considered. Therefore, if abnormal vaginal bleeding occurs, it is recommended to consult a doctor in a timely manner, complete the relevant examinations, and identify the causes under the guidance of a professional doctor, so as to avoid delaying the condition.
